Given they are closed at the moment, you may have a tough time reaching anyone that can confirm a cancellation. Document contacts you have made and the results to show your intent. You may also try a written letter to the address to see if there is any response. The only other option would be to close the account used to book the stay and hope your CC does not forward the charge to the new account.
